However, as announced earlier today, the Queen and Prince Philip are absent from the celebrations.

Prince Louis is wearing a handmade replica of the Royal Christening Robe, made by Angela Kelly, Dressmaker to The Queen. Louis will become the eighth royal baby to wear the gown.

Why isn’t the Queen attending?

Kensington Palace released a list of those attending the service this morning – and Her Majesty and the Duke of Edinburgh weren’t on it. The pair attended both Prince George’s christening in 2013 and Princess Charlotte’s in 2015. There’s no official explanation on why the most senior royals are skipping their great-grandson’s christening, but it appears it’s not due to ill health.

The Queen & Philip have just spent the weekend together in Norfolk. He is remaining there while she travels back to London today. Her decision not to attend was mutually agreed with William & Kate, while Philip clearly doesn’t want to attend public events unless he really has to.

Who are Prince Louis’ godparents?

Louis’ godparents are a mix of close friends and family members: Nicholas van Cutsem, Guy Pelly, Harry Aubrey-Fletcher, The Lady Laura Meade and Robert Carter are all friends of the Duke and Duchess’ and and Lucy Middleton is Kate’s cousin.

Which readings and hymns are included in the service?

The Duke and Duchess have chosen two hymns, two lessons and two anthems for their son’s christening, tweets royal correspondent Russel Myers.

Who’s taking Prince Louis’ official christening portraits?

According to royal correspondent Richard Palmer, Matt Holyoak will take the family photos.

The Duke and Duchess of Cambridge have asked portrait photographer Matt Holyoak to be the official photographer at the christening of Prince Louis. Mr. Holyoak will take the official photographs at Clarence House following the service in The Chapel Royal, Kensington Palace says.

Following the service, the Duke and Duchess of Cambridge will give a private tea at Clarence House. Guests will be served slices of christening cake, which is a tier taken from the Duke and Duchess of Cambridge’s wedding cake.
